FIELD OF THE DISCLOSURE

This disclosure, in general, relates to containers for liquid media and interfaces for attaching such containers to instruments.

BACKGROUND

Increasingly, laboratories are seeking instruments to perform testing of analytes. Preparation of such instruments can be labor-intensive, relying on the time-consuming preparation of reagent solutions. To reduce preparation times, industry is turning to pre-made reagent solutions provided to laboratory customers in kits. But, the shipping and handling of liquid reagents can lead to degradation of the reagent and spillage. As such, an improved reagent container and instrument interface would be desirable.

DETAILED DESCRIPTION

In an exemplary embodiment, an instrument includes a fluidics interface to receive a removable container. The instrument side interface can include ports, such as a liquid port or a gas port. The removable container can include complementary ports, such as a liquid port and a gas port. In a particular example, a top of the container includes a swing bar to couple with a cradle of the instrument side fluidics interface. Once the swing bar and cradle are engaged, the container can swing into place to engage the fluidics interface of the instrument. In a particular example, the cradle is positioned outward from the instrument relative to the fluidics ports.

In an example illustrated in FIG. 1, an instrument 100 can include a panel 102 having a recess 104 to receive a container 108. The container 108 can have a top configured to engage a fluidics interface 106 of the instrument 100.

For example, as illustrated in FIG. 2 and FIG. 3, the fluidics interface 106 can engage a top 210 of the container 108. In particular, a swing bar 212 of the top 210 of the container 108 can engage a cradle 214 of the fluidics interface 106. The container 108 can swing into place, engaging fluid manifold 216 of the fluidics interface 106 of the instrument.

In a particular example illustrated in FIG. 4, the container 108 can include a top 210 having a fluidics interface 420. As illustrated, the fluidics interface 420 is axially centrally located along an axis of the container 108 and top 210. To one side of the fluidics interface 420 on the top 210 is positioned a swing bar 212, which can form part of the top 210. Optionally, opposite the swing bar 212 relative to the fluidics interface 420 is a counter structure 418.

Optionally, the top 210 of the container 108 can be connected to a sipper 522 residing within the container 108, as illustrated in FIG. 5. At a distal end of the sipper 522, a filter 524 can be attached. In a particular example in which the container 108 is to store a reagent including solids chemistry, such as solid-state buffers, the reagent solution can be drawn through the filter 524 and sipper 522 and out of the fluidics interface 420.

As illustrated in more detail in FIG. 6, FIG. 7, and FIG. 8, the top 210 of the container 108 includes the fluidics port 420 centrally located along an axis of the container 108, and optionally concentric with the top 210. When viewed from above, as illustrated in FIG. 6, the swing bar 212 is disposed on an opposite side of the fluidics port 420 from a counter structure 418. For example, a line can extend across the upper surface of the top 210 through the center of the swing bar 212, the fluidics port 420, and the counter structure 418.

As illustrated in FIG. 6 and FIG. 7, the fluid interface 420 can include a peripheral sealing ring 626. A liquid port 630 comprising a raised sealing structure can be disposed at an axial center of the fluidics interface 420. In an example, a gas port 628 can be disposed to a side of the liquid port 630 and within the boundary of the sealing ring 626. As illustrated in FIG. 8, an underside of the top can include the fluidics port 630 centrally located and an opening to the gas port 628.

Such a configuration of the top 210 of the container 108 and the associated liquid and gas ports can effectively receive a complementary lid during shipping. Such a configuration can limit fluid leakage.

FIG. 9, FIG. 10, and FIG. 11 include illustrations of an exemplary instrument side fluidics interface 106. The fluidics interface 106 includes a cradle 214 and a fluidics port 216. In particular, the cradle 214 is disposed further from the instrument panel than the fluidics port 216.

As illustrated in FIG. 10, the fluidics interface 106, when viewed from an underside, includes a sealing structure 1032 to engage the sealing ring 626 of the container 108. In an example, a liquid port 1034 extends and can engage or enter the liquid port 630 of the container 108. Alternatively, the liquid port 630 of the container can enter the liquid port 1034 of the fluidics interface 106. Optionally, a gas port 1036 can be provided to access the gas port 628 of the container 108 by virtue of the seals formed between the rings 1032 and 626, as well as the seal formed by the liquid ports 1034 and 630.

As further illustrated in FIG. 10, the fluidics interface 106 can include a recess 1038 to receive the counter structure 418 of the top 210 of the container 108. As illustrated in FIG. 11, connectors 1142 can be positioned on one or both sides of the recess 1038 and can releasably secure the counter structure 418 in place.

As further illustrated in FIG. 11, the cradle 214 includes a recess 1144 to receive the swing bar 212. For example, as illustrated in FIG. 12, the cradle 214 includes a recess 1144 and a slot 1246 to receive the swing bar 212 of the container 108 and allow the container 108 to swing towards the instrument and engage the connectors 1142 and the fluidics ports 1034 and 1036.

In use, the swing bar 212 of the top 210 of the container 108 can engage the cradle 214 of the fluidics interface 106 at an angle. The container 108 can then swing along around a pivot formed by the cradle 214 and swing bar 212 into the recess 104 of the instrument 100. The counter structure 418 can engage the recess 1038 and optional connectors 1142. In a particular example, the weight of the bottle and optional connection to the connectors 1142 forms a leak-tight seal between the fluidics ports 420 of the container 108 and the fluid manifold of the fluidics interface 106. Optionally, air can be applied through the gas ports and into the container 108. The liquid reagent solution within the container can be drawn or pushed through the liquid port 630 and into the instrument 100. To disengage the container 108, the process can be reversed.

While the examples illustrated herein include a cradle in the instrument side fluidics interface and a swing bar on the top of the container, the container can alternatively include the cradle and the instrument side fluidics interface the swing bar. In another alternative example, the positioning of the liquid port and the gas port can be reversed or can be disposed in different positions with different male or female configurations.
